I don’t train with free weights very often, but when I do I like to do the following 5 exercises:
Pushups with rows while using a DB,
DB squat and overhead presses,
Pull-ups with DB,
DB see-saws while walking,
walking lunges with DB bicep and over head presses
I usually do them in a row by completing a specific number of repetitions on each exercise before I move to the next one.
